looking for nash of PA.

I am looking for Edward Nash born in Washington co. PA. in 1772. All I know about him is his wifes first name is Altheia. Born in 1776. Edward and his wife and son Jerimiah Nash, born in 1801 in Washington Co. PA.
Along with Rev. Benidict Belt, Anna Elizabeth Belt,John Belt,James Petticord and many others to Cherry Valley and Licking Co. Ohio. I am looding for any info on either Edwards or Altheia's parents.
